Abstract :
In this paper, the new structure of high rate non-binary QC-LDPC codes based on the circulant permutation matrices is proposed. The construction of parity-check matrix of the proposed codes is obtained from (2, L) regular QC-LDPC codes. The parity-check matrix of the proposed codes has girth greater than 8. Simulation results over PR channels with the high order Galois Field show that the bit error rate and the symbol error rate performance of the proposed codes is better than those of the random non-binary LDPC codes, both in PR2 channel and EPR2 channel.
